Automatic Transmission Fluid
How to Check Automatic Transmission
Fluid
It is not necessary to check the transmission fluid level.
A transmission fluid leak is the only reason for fluid
loss. If a leak occurs, take the vehicle to your dealer/
retailer service department and have it repaired as soon
as possible.
There is a special procedure for checking and changing
the transmission fluid. Because this procedure is
difficult, you should have this done at your dealer/
retailer service department. Contact your dealer/retailer
for additional information or the procedure can be found
in the service manual. To purchase a service manual,
see Service Publications Ordering Information
on
page 8‑16.
Notice: Use of the incorrect automatic transmission
fluid may damage the vehicle, and the damages may
not be covered by the vehicle's warranty. Always
use the automatic transmission fluid listed in
Recommended Fluids and Lubricants on page 7‑10. Change the fluid and filter at the intervals listed in
Scheduled Maintenance
on page 7‑3, and be sure
to use the fluid listed in Recommended Fluids and
Lubricants on page 7‑10.
Manual Transmission Fluid
It is not necessary to check the manual transmission
fluid level. A transmission fluid leak is the only reason
for fluid loss. If a leak occurs, take the vehicle to your
dealer/retailer service department and have it repaired
as soon as possible. See Recommended Fluids and
Lubricants
on page 7‑10for the proper fluid to use.
Hydraulic Clutch
It is not necessary to regularly check clutch fluid unless
you suspect there is a leak in the system. Adding fluid
will not correct a leak. A fluid loss in this system could
indicate a problem. Have the system inspected and
repaired.
